critical Tenable Self-Hosted Container Security Plugin ID 439492

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Versions of the package jsrsasign from 7.0.0 and before 11.1.1 are vulnerable to Incomplete Comparison
with Missing Factors via the getRandomBigIntegerZeroToMax and getRandomBigIntegerMinToMax functions in
src/crypto-1.1.js; an attacker can recover the private key by exploiting the incorrect compareTo checks
that accept out-of-range candidates and thus bias DSA nonces during signature generation. (CVE-2026-4599)
